Hi. Is there any one the FE'ers who spent some time on Flight Simulator worlds (e.g. Microsoft FSX)? They have a perfect model of the round earth with all existing features in 100 m. resolution, viewable at any angle and altitude. Well, yeah, you can say that it's a simulation, a computer created world but how come it perfectly matches the one we have in real life? Flight times, locations, distances, time zones; day and night, etc. working with round world maths... If the earth was flat, there should have been some inconsistency with this round model...
